The parameter transmission between the brain and the Mission Planner has became extremly slow. It takes 5 minutes to update the parameter list! And the blinking pattern of the erle brain is kind of irregular, sometimes slow pace and sometimes fast blinking and sometimes even keep red.

The update rate seems to be really slow too. Good new being, the PX4FLOW sensor gives some value back at flow_x_comp, Values change almost only every couple seconds for the PX4FLOW. The imu data in comparison was a bit faster, but still way slower than normal.

when i run the new ardupilot it crushed on occasion for now reason. The ESC would not receiving signals for several seconds until is runs again. Btw, this happened before when I compiled other new version of ardupilot from source too.

Could you try to reproduce this? I have Erle brain 3, flashed new image, using your deb package, with only pwm signal attached, powered by 2.25 A power module and a 3s battery.It's a shame because the PX4flow and LidarLite v3 sensor seems to work but I won't dare flying the drone at its current state. Thanks!

I did a clean build with the beta debian package but it happened again.. I have no idea whats going on now..

I have been trying to gdb the ardupilot and reproduce the issue, but no success.

If I run the autopilot separately using gdb or execute the binary after system boot , it seems to run fine in idle. But when I just plug in and start automaticlly the ardupilot would crush (red light blinking).

Could you provide an explanation of the startup sequence? Maybe there is something wrong there.
